Help me to solve this problem

anyanavicka [17]

Here,

Volume of cylinder = 539^3 cm

Circumference = 22 cm

Height = ?

Now,

Circumference = 2πr

or, 22 = 2*22/7*r

or, 22 = 44/7*r

or, 154/44 = r

◆ r = 3.5 cm

Then,

Volume of cylinder = πr^2h

or, 539 = 22/7*(3.5)^2*h

or, 539 = 22/7*12.25*h

or, 539 = 269.5/7*h

or, 3773 = 269.5*h

or, 3773/269.5 = h

◆ h = 14 cm

I hope it's help you...

I hope you understand...

What is the mean for Doctor A’s data set on corrective lenses? What is the mean for Doctor B’s data set on corrective lenses? Wr

Nat2105 [25]

Answer: Doctor A: 751.6 Doctor B: 755.2 Doctor B has an average of 3.6 more patients wearing corrective lenses than Doctor A.

Step-by-step explanation:

To find the mean for corrective lenses, add up all of the numbers and divide by the number of data points.

Doctor A's mean:

Add up the data points: 745+726+769+765+756+742+747+748+770+738 = 7516. Count the number of data points to get 10. Divide 7516 by 10. 7516/10 = 751.6.

Doctor B's mean:

Add up the data points: 763+736+735+759+748+756+765+761+768+761 = 7552. Divide by 10. 7552/10 = 755.2

Difference:

755.2-751.6 = 3.6

Both triangles are similar. The area of the larger triangle is about 382 ft2. Which is the best approximation for the area of th

melisa1 [442]

Answer: SECOND OPTION

Step-by-step explanation:

You must find the ratio of the sides of the triangle, as following:

$r=\frac{30}{42}=\frac{5}{7}$

Therefore, the ratio of the areas is:

$r_A=(\frac{5}{7})^{2}\\\\r_A=\frac{25}{49}$

Now you must multiply the area of the larger triangle by the ratio obtained above, therefore, you have that the result is:

$A_s=(382ft^{2})(\frac{25}{49})=194.89ft^{2}$ ≈ $195ft^{2}$
